SPECIFICATION forming part of Letters Patent No. 393,871, dated December 4, 1888. Application filed MayS, 1888. Serial No. 272,732. (No model.)

To all 207mm it muy concern.:

13e it known that T, FERDINAND WEINBEEN- NER, a subject of the King of Prussia, residi )Iy invention relates to improvements in organ-stops, by which any required stop or I group can be brought into action by means ot' i i s i l i i l a. lever operated either by the knee or foot f or other means.

On the shaft A of the grand organ, which y olo, forte, ttc.

is operated in the usual manner by the knee or feet or other means, are arms C for each stop-shaft Il. rectly on the cranked part of the shaft B, but through the plate D, which lies between them. This plate D is of such a form and arranged in such a manner that when it is displaced by pulling the stop-handle F the arm I This arm C does not press di- C catches on it and shoves it into its original l position later or earlier than if it had not been displaced according to its position. The

object of this is, that those stops only whose plates C are displaced will be opened at different times by the grand-organ stop. These plates D can be displaced, so to open the stops sooner or later in relation to one another.

when the stop is not actuated by the arm C of the shaft A till the arm C arrives at f3, Then i shown in Fig. Q-that is, with the stop on or ready to bc put in action-the arm will open the stop suddenly, when the grand-organV` shaft begins its first motion.

Fig. 3 shows a top view of the improved stop in the position as seen in Fig. l. Fig. l is a section through the line .r y, Fig. l.

E is a. guide for the plate I), which prevents it from rising too high or from falling to the side.

Stops which in general are not opened by the grand-organ stop-as, for instance, tremcan be so arranged that the arm C does not catch on the plate D when the plate D is in its original position, while it may catch on it after being put in action.

The plate I) can be adjusted by means of a key or other means above or below the stophandle F or b v the handle F itself. In both cases can the plate D be connected immediately to the key. 'lhe plate D can also be connected to a separated shaft, G, as shown in the drawings.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In an organ stop-action, the arms C, o'e-r 1 described. Figure l shows the position of the plate I) i 2. ln an organ stop-action, the arms C, one

for each register, fastened to the grand-organ shaft A, with the stop-axle B and the movable plate D, arranged between C and B, for the purpose as described.

3. III an organ stop-action, the arms C, one for each register, fastened to the grand-organ shaft A, with the stop-axle B and the movable plate D, arranged between C and B, and the movable handle F, fastened to the plate D, for

from a to without affecting the position of the plate D, and therefore will not affect the stop itself, as shown in Fig. 1; but when the arm C moves from to y it will then open the stop-axle B by depressing the plate B; but, as

the purpose as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

FERDINAND WEINBRENER.
